I recently purchased an RTX 5070 for my PC, thanks to everyone's help in my previous thread. However, I've noticed that my power cable configuration isn't the best; it's technically daisy chained, which isn't ideal for power efficiency. Currently, I'm using two 6+2 pin connectors, and I'm concerned if that's not sufficient.
I have a Corsair TX650M PSU, which doesn't support ATX 3.0, so I'm thinking I need an additional 8-pin cable to connect from the PSU to the GPU adapter, ensuring it's not coming from the same wire as the other 8-pin connector.
The issue is that I can't find many male-to-male dual 8-pin connectors online. Do I definitely need to find an 8-pin to 8-pin connector to eliminate the daisy chaining concern? Or can I simply use two separate 6+2 connectors from different slots on the PSU?

Honestly, the TX650M can handle a 5070 even with a single daisy-chained cable. The 5070 has a TDP of 250W, and each 6+2 connector is rated for 150W, which is usually more than enough. Many users report that the card runs efficiently, often drawing under 150W even during intense gaming. So, as long as your setup is stable and you're not experiencing issues, you may not need to rush into getting a new cable.
Just be cautious with a single cable if you're concerned about heat or efficiency. It's good to have backup options!
Using two separate 6+2 pin connectors from different PSU slots is perfectly fine! It should work well for your RTX 5070 without causing any issues. Just make sure both connections are secure, and you should be good to go!
That's reassuring! So as long as I use two 6+2 connectors running separately, I should be fine? I'm new to all this and getting mixed advice.
